Definitions

  • the present invention relates to a method and a machine for shaping edges of glazing.
  • the edges are sharp and they also have defects, which could constitute incipient fractures at the time of tempering if they were not removed beforehand, by grinding using a machine of shaping.
  • the commonly used shaping machines comprise at least one grinding wheel for shaping the edge of the glazing, a template similar in shape to that of the glazing, arranged parallel to this and in the centered position, a roller mounted on the axis of the grinding wheel and resting on the template in order to guide the grinding wheel along the edge of the glazing, means for holding the glazing to be worked, constituted by two jaws, lower and upper, which come to tighten it tightly and means for bringing the glazing, centering it and evacuate it.
  • the jaws which hold the glazing in place during the shaping of its edges to resist the high pressure of the grinding wheel must be largely dimensioned and powerful, which further increases the cost of such machines.
  • the size of these jaws prohibits the treatment of small glazing as well as the simultaneity of the shaping operation and the approach of the means of supplying and evacuating the glazing, resulting in a reduced production rate. .
  • the present invention aims to remedy all these drawbacks of conventional shaping machines to obtain better quality of shaping, better yields and better rates, and this with less expensive machines.
  • the invention provides an automatic process for shaping the edges of glazing in which the grinding wheel is no longer guided by a template but by the glazing itself.
  • the method according to the invention essentially consists in presenting the glazing facing the rotating grinding wheel, in rotating the glazing on itself so as to scroll its entire periphery in front of the grinding wheel while keeping the grinding wheel pressed against the edge of the glazing.
  • the bearing force of the grinding wheel on the glazing can be much lower, less than 10 kg and in general from 4.5 to 6 kg.
  • the maintenance of glazing during the shaping can be less powerful and the holding means less bulky, so that it becomes possible to simultaneously practice the shaping and the approach of the supply and / or evacuation means. glazing.
  • the present invention also relates to a shaping machine for implementing this method and which comprises a grinding wheel guided by the edge of the glazing, a vacuum plate to keep the glazing stationary and which is arranged on one side of the glazing, means for supplying and removing glazing, such as conveyors, means for transferring glazing between the feeding means and the plate on the one hand, and between the plate and the means for discharging on the other hand, and a logic control system capable of modulating the speed of rotation of the glazing and the pressure of the grinding wheel on the glazing.
  • the shaping machine essentially comprises a vertical pivot 10 provided at its upper end with a vacuum plate 12, connected to suction means for holding a glazing unit 14.
  • the pivot 10 is driven in rotation by a reduction motor 16, so that the glazing unit 14 successively has all the points of its periphery in front of a rotary grinding wheel 18 carried at the end of a horizontal arm 20 pivotally mounted on a column 22.
  • the glazing rests on the plate with the interposition of a peripheral seal 15 ( Figures 2 and 3).
  • the suction port 17 opens into the chamber defined inside the seal under the glazing.
  • the glazing is supported in the vicinity of its center by an elastic patch 19.
  • the grinding wheel is pressed against the edge of the glazing by a pressure cylinder 24, and it can be moved relative to the glazing by a reversing cylinder 26.
  • the pressure of the grinding wheel 18 on the glazing and the speed of rotation of the pivot 10 are controlled by a program specific to each glazing model, introduced into the logic system which controls the entire machine.
  • the pressure of application of the grinding wheel on the glazing is a function of the distance between the axis of the grinding wheel and the axis of the pivot 10, and of the speed of rotation of said pivot 10.
  • the information concerning the operation of the machine can be viewed, in particular, the distance d can be viewed by a needle 27 integral with the pivot 10 and moving in front of a graduated scale 31 ( Figure 2).
  • the glazing units are brought to the shaping station by an upstream conveyor 28 and are evacuated by a downstream conveyor 30.
  • the transfer between these conveyors and the vacuum plate 12 is carried out by a mechanism comprising a rolling carriage 32 driven by motor means on a horizontal guide rail 34 disposed above the conveyors 28, 30 and of the plate 12.
  • the carriage is fixed by its middle, a horizontal rod 36 provided at its ends with suction cups 38, 40 capable of coming into engagement simultaneously with two glazing units 14, respectively placed on the upstream conveyor 28 and on the plate 12.
  • the guide rail 34 can be raised or lowered by a lifting cylinder 42.
  • FIGS 4 to 7 show a practical embodiment of the machine according to the invention.
  • the homologous elements of these figures and of Figures 1 and 2 will bear the same numerical references.
  • the whole machine is mounted on a metal frame 50.
  • the pivot 10 of the vacuum plate 12 is rotated by the reducer 16 which is itself driven by a variable speed motor 52 via a cardan transmission 54.
  • the motor 50 is powered by a tacho dynamo 56 .
  • the wheel pressure cylinder 24 is pivotally mounted about a vertical axis 58 carried by two horizontal plates 60, 62 fixed on a pillar 64.
  • the cylinder rod 66 is provided with a stirrup 68 receiving between its branches a fin 70 which protrudes from the wheel arm 20.
  • Said branches of the stirrup and said fin are secured by means of a screw or the like, passing through a hole 72 drilled in the fin 70.
  • the couple acting on the wheel arm 20 can be preset by choosing the hole 72 from a series of holes more or less close to the axis of the column 22 around which the wheel arm pivots.
  • Column 22 also carries a console 74 on which is fixed a driving pulley 76 driven by a motor 79 (FIG. 6) and whose rotational movement is transmitted to the head 78 of the grinding wheel by a belt 80.
  • a driving pulley 76 driven by a motor 79 (FIG. 6) and whose rotational movement is transmitted to the head 78 of the grinding wheel by a belt 80.
  • the reversing cylinder 26 is fixed on the pillar 62 and its rod bears on a stop 82 ( Figures 3, 4 and 6) integral with the column 22.
  • a stop 82 Figures 3, 4 and 6 integral with the column 22.
  • the arm 20 and the grinding wheel 18 can be brought to different positions. In FIG. 7, the arm 20 is shown in two positions corresponding to two glazings 14, 14 'of different dimensions.
  • the glazing transfer mechanism between the conveyors 28, 30 and the vacuum plate 12 is suspended from a bracket 84 reinforced by shutters 86 ( Figures 4 and 6). It comprises a horizontal fixed beam 88 and a horizontal movable beam 90 arranged under the beam 88.
  • the beam 90 can be translated parallel to the beam 88 by means of a linkage comprising a rod 92 fixed to the rod of a lifting cylinder 52 and two double levers 94, 96 bent, pivotally mounted around axes 98 which pass through d on the one hand, said levers at their apex and, on the other hand, stirrup arms 100 overlapping the fixed beam 88 in the vicinity of its ends.
  • the upper arms of the bent levers are respectively articulated on an axis 102 carried by the rod 92, while the lower arms are articulated on an axis 104 carried by the movable beam 90.
  • the movable beam 90 carries a rodless cylinder 106 in which is slidably mounted a piston to which the rolling carriage 32 is suspended.
  • the latter is provided with rollers 110 which roll on guide rails 112 resting at their ends on load-bearing structures 114 , 116 fixed to the ends of the movable beam 90.
  • the carriage 32 also carries vertical plates 118, 120 elongated in the horizontal direction, at the ends of which the suction cups 38, 40 are fixed.
  • the grinding wheel can be pressed against the glazing with a force much lower than that used in template machines.
  • a pressure of 4, 5 to 6 kg is generally enough to perform a good shaping.
  • the suction cup transfer system can move freely and come to a position ready to take care of the glazing placed on the upstream conveyor and on the suction cup plate. The shaping rate is therefore faster than in the case of template machines.
